This collection of articles by officers of the Indian Army records the contributions of the Army to natural history over a period of more than two hundred years. It builds on the premise that the study of the Indian subcontinent's natural history was more or less the exclusive preserve of these officers. Beginning with the fading years of the eighteenth century, the natural history-inclined officers of the Indian Army studied the flora and fauna, particularly thefauna, in their leisure hours and became experts on it. Their findings were recorded in various journals in the U.K., and after 1886 mainly in the Journal of the Bombay Natural History Society. A valuable feature of this book is a pamphlet (the twenty-fifth article in the collection) sent to the Indian Government by the Army through the Society by Lieutenant Colonel Burton, which drew the attention of the former to the dire need to conserve the country's wildlife, and in due course saw the formation of the Indian Board for Wildlife. The book is thus a tribute to this remarkable aspect of the Indian Army which, apart from fighting in the field, fought a battle to conserve the country's wonderful and almost incomparable natural heritage spread over a zoogeographical area over thirty degrees of latitude encompassing almost every type of climate met with in the world.
